Fig. 5From: Genome-wide analysis of the CCT gene family in Chinese white pear (Pyrus bretschneideri Rehd.) and characterization of PbPRR2 in response to varying light signalsPhotosynthetic performance of PbPRR2 transiently expressed in tobacco with increasing R light intensity. Leaves were infiltrated with PbPRR2 (red line) or the control pHEX2-GUS (blue line). Data for three key photosynthetic parameters, i.e., net photosynthetic rate (A), stomatal conductance (B) and internal CO2 (C), are presented as the mean ± SEM (n = 20). Asterisks indicate significant difference at P < 0.001Back to article page
